the lie fiat type, as disclosed in the United States Letters Patent 8 29217, granted April 2, 1907, wherein the pin or thrust member extends across the back or body member of the pin. In this type of safety pin the back member is provided with an offset or hump between its ends so as to provide sui'ficient clearance between the thrust and back members to accommodate the cloth.

The object of the present invention is to provide this clearance between the thrust and back members without resorting to the hump or effect portion and leaving looth of such members straight or substantially so, This result is accomplished by providing a coil of one or a plurality of convolutions at the junction between the thrust and back members, as distinguished from the single bend of the patented structure above r The more the con cluticns in the coil the greater will he the space between the thrust and back members, and. conse quently in pins intended for very thick fahric it is preferable to use more than one coil.

With such objects in view, whichwill appear as .-.SC?ipli-l0i1 coeds, the invention comprises various no features of construction arrangement a parts which will he set fortwith particulari y in icilowing misc n vent-ion 1; reference all the views,

rig. 6 is side View of a safety pin having a coil formed of a plurality of convolutions.

Referring to the drawing, 1 designates the thrust or pointed member of the safety pin, 2 the hack member or body, 3 the coil,

and L the cap or guard, which latter may be of any approved construction, as it forms no particular part of the present invention, except that theopening ofthe mouth 5 of the guard opens inwardly or toward the back member 2. The members 1 and 2 cross each other adjacent the coil 3, and they are permanently separated or out of contact by reason of the convolutions of the coil, the axis of the coil being at right-angles to the plane of the safety pin as a whole. In other words, between the members 1 and 2 are one or more convolutions 6, as in Figs. 1 to 4: inclusive, or a plurality of convolutions 7, as shown'in Fig. 6. It will thus he seen that the hack member 2 need not be bent, overset' or humped, as in the said patent Jereinhefore referred to, for providing clearance between the members 1 and 2 for accommodating the thickness of the cloth fastened by the safety pin. The safety pin is applied in the usualmanner to the article or articles to be pinned, and when the point of the thrust member is engaged with the cap or guard, the pin lies flat on the article or articles pinned, the advantage of which apparent.

From the "foregoing descrintion taken in connection with the accompanying drawing,

the advantages of the construction and co the emhodiment thereof, I desire and that such changes when desired as fall within appended clai' descrhed my invention, I

desire to secureby Let- V- or pin comprising thrust and body disposed in crossing relation spaced from each a. coilconnect- 1;? inemhers together at one end I r 1e and a graard the opposite end he pin w having; mouthcpening body inemher, the point of crossierstood that the article shown ing of the members being sligh'iy spacefi inwardly from the coil.
